- CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 278,577, dated May 29,1883.

Application filed November 14, 1882. (No model.)

simplify and cheapen the cost, and in contrivances for fastening andadjusting the parts, and also in a clod-fender attachment, all ashereinafter fully described, and pointed out in the claims.

Reference isto be had to the accompanying drawings, forming part ofthisspecification,in

which similar letters of reference indicate corresponding parts in allthe figures.

Figure l is a perspective view of my improved cultivator. Fig. 2 is alongitudinal section of the same, and Fig. 3 isa plan wiew.

I make the beam of two thin partsof wood plank, a,placed side by side,and secure the plow-stocks b c and the colter-stock d to it by clampingthem between the said parts a by bolts eand f, the parts being boltedtogether at-the front end by bolt g. This atrangement makes a lighterbeam, and is also stronger for the same amount of material,

and saves the cutting of mortises through it. The bolts f, before andbehind the colter dandplow-stock c, are also arranged one above another,so as to control the pitch of the colter and front plow, g, and thepitch is varied by means of the keys h'. The transverse dimensions ofthe. stock 0 and colter d being alike, and the bolts f being arrangedalike for each, enables the plow g to be set in the place of the colterwhen the latter is not required for use, and the colter may be set inthe place of. the plow when the latter is not required. The verticaladjustment of the plow-stock c and colter d is accomplished by simplyshiftin g them up or down when the boltsf are slackened a little. Thebolt e for the plow-stock 11 passes through a slot, i,in the stock,allowing it v to shift up and down, and a series of holes, j,

is made in the beam for the bolt, enabling it to be set in differentpositions forward and backward. The adjusting screw 1 and the brace ksecure the stock I) in the required pitch or inclination with respect tothe beam, and the beam is also regulated as to the height of the frontend from the ground by them.

The handles m are adjustable vertically by shifting theirconnecting-bolt a up and down along the series of holes 0 in the lowerend of the stock, where they are bolted to it; also by shifting thecrossbar 12 in the sldt q of the upper end of the stock I), where saidbar is clamped fast by the bolts 8 to secure the handles in position.The handles may also be shiftedlaterally by the bar 19 and slot q toenable the plowman to follow in the furrow or out, as he may desire.

The clod-fender t, which consists of a simple piece of board, is boltedonto the beam in front of the colter by bolt u, together with anotherbolt, 21, and a gib, a, which are adjustable along the slot at, by whichthe set of a the fender is adjusted as may be required.

The plow w is bolted onto the stock b by bolt y, with washers 2, havingleather packing between them, making a kind ofexpansion device thatenables the bolt to hold the plow in position without any shoulder onthe stock, so that the front of the stock may be plain for theapplication of plows of different forms for different kinds of work.

.As represented in the drawings, the plows are adjusted for barring off,but they may be otherwise set. For instance, two righthand plows ofcommon form maybe set for plowing and snbsoiling at the same time. Oneright-hand and one left-hand plow may be set for turning the furrow bothways, and other adjustments may be made. 7

Having thus fully described my invention, I

claim as new and desire to secure by Letters I Patent- 1. Thecombination, with the beam, of the slotted plow-stock b, the bolt 6, andthe screw l, substantially as herein shown and described.

2. The combination, with the beam, of the slotted plow-stock b, the bolt0, the screw 1, and the brace 70, substantially as herein shown anddescribed.

3. The combination, with the two-part'beam a a, provided with the holesj in its rear end, of the slotted plow-stock b, the bolt 0, the screw 1,and the adjust-able brace 70, substantially as herein shown anddescribed.

4. The handles m, connected to stock I) by bolt at, bar 12, and slot q,the said stock being provided withthe clamping-bolt s, substantially asdescribed.
